Abstract

PROBLEM TO BE SOLVED: To provide a method for finishing the surface of a tufted carpet, by which the tufted carpet to whose back side an anti-slipping backing material comprising a rubber layer is adhered can be subjected to a smooth hair-handling process and then surely transferred to the next polishing process and the shearing process. SOLUTION: In the hair-handling process, a rotary support roll is used as a support member for supporting the backing material of the tufted carpet and simultaneously forward guiding the tufted carpet. Even when the tufted carpet to whose back side an anti-slipping backing material comprising a rubber layer has been adhered is transferred, the rotary support roll supporting the tufted carpet is smoothly rotated in response to the transfer speed to reduce a rubbing contact frictional force between the rotary support roll and the anti- slipping backing material, thus surely, smoothly and sequentially continuously supplying the tufted carpet to the polishing process and the shearing process to finish the surface piles of the carpet.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface finishing method for finishing a surface pile of a tufted carpet having a backing.

[0002]

2. Description of the Related Art Conventionally, a tufted carpet manufactured by sticking a backing material to a carpet main body that is tufted to a base cloth using a tufting machine,
After finishing the pile pile on the surface in the final process,
Surface finish is given through polisher process to give pile gloss and shirring process to align pile height,
It has been commercialized.

[0003] In the above-described hair treatment step for finishing the surface of the tufted carpet and the polisher step and the shearing step, the hair treatment step, which is the first surface treatment step, as shown in FIG. The fixed guide member 23 includes a brush roll 21 and a fixed guide member 23 having an upper end portion formed on a tapered arc-shaped guide surface 22.
The pile on the surface of the tufted carpet 10 is brushed (split) by the brush roll while sliding on the arc-shaped guide surface 22.

[0004]

However, since the tufted carpet 10 is moved while sliding the backing material 11 on the back surface thereof against the arcuate guide surface 22 at the upper end of the fixed guide member 23, Friction will occur between 11 and the guide surface 22. In this case, in a tufted carpet in which the backing material is directly adhered to the back surface of the base cloth and the back surface of the backing material is formed as a smooth surface, the tufted carpet replaces the smooth surface of the backing material. It moves relatively smoothly while bending along the arcuate guide surface 22, so that hair removal processing can be performed, but a backing material is attached to the back of the base fabric via a sound absorbing elastic layer made of sponge of appropriate thickness. In the case of tufted carpets and tufted carpets in which a non-slip backing material is adhered to the back of the base cloth, it is difficult to remove the hair, and therefore, the polisher or shirring, which is a post-process, cannot be performed. There is a point.

The reason is that the tufted carpet, in which a backing material is adhered to the back surface of the base cloth via a sound-absorbing elastic layer made of sponge with an appropriate thickness, is formed by the arc-shaped guide of the fixed guide member 23. When passing through the surface 22 while refracting it in an inverted V-shape in contact with the surface 22, the backing material becomes small wrinkled due to the refraction, and the guide surface 22 of the fixed guide member 23 compresses the sound absorbing elastic layer due to the presence of the sound absorbing elastic layer. The backing material is strongly pressed against the backing material while being deformed, so that the frictional force between the backing material and the fixed guide surface 22 increases, and the fixed guide surface 22 pressed against the backing material in a damped state is used. This is because the wrinkled state is accumulated with the passage of the tufted carpet, and eventually, the backing material is separated from the sound absorbing elastic layer.

In the latter case, that is, in a tufted carpet in which a non-slip backing material is adhered to the back surface of the base cloth, the non-slip surface of the backing material and the arc-shaped guide surface 22 of the fixed guide member 23 are used. Is extremely large, and the tufted carpet cannot be smoothly moved to the polisher process section.

The present invention has been made in view of such problems, and has been made in consideration of the above circumstances, and has been made of a tufted carpet or a base having a backing material adhered to a back surface of a base cloth via a sound absorbing elastic layer made of a sponge having an appropriate thickness. Even for tufted carpets with a non-slip backing material adhered to the back of the cloth, the hair treatment process is performed smoothly through the hair treatment process with almost no frictional resistance, and the next polisher treatment It is an object of the present invention to provide a surface finishing method for a tufted carpet that can surely perform a shearing process.

[0008]

In order to achieve the above object, a method for surface finishing a tufted carpet according to the present invention comprises the steps of: providing a tufted carpet having a backing; In a method for finishing a tufted carpet in which the surface pile is successively fed to a hair treatment step, a polisher step, and a shearing step to finish the surface of the pile, the brush treatment for the brush roll for the hair treatment in the hair treatment step is performed. A rotary support roll is used as a guide that presses the tufted carpet, and the pile of the tufted carpet is cleaned while rotating the rotary support roll by running the tufted carpet.

In the method for finishing a tufted carpet surface, the invention according to a second aspect is characterized in that the tufted carpet fed into the hair-pulling process section has a sound absorbing elastic layer on the back surface of the carpet main body formed by tufting the base cloth. Tufted carpet, with a backing material stuck together,
Alternatively, it is a tufted carpet in which a non-slip backing material is adhered to a back surface of a carpet main body tufted on a base cloth.

[0010]

When the tufted carpet is supplied between the brush roller for brush and the guide to perform the bristle treatment, the guide for supporting the lining material of the tufted carpet is formed by a rotating support roll. Even if the rotation support roll rotates in synchronization with the feed speed of the tufted carpet and the back surface of the backing material is formed of a non-slip rubber layer, or the backing material is formed through a sound absorbing elastic layer such as a sponge. Even if the surface pile is adhered, the surface pile is treated by the brush roll with little frictional resistance against the rotating support roll. Therefore, the tufted carpet can be reliably and smoothly continuously supplied to the next polisher process section and the shearing process section via this hair-pulling process section, and the tufted carpet having the sound absorbing elastic material layered on the back surface, Even a tufted carpet on which a rubber layer or the like has been subjected to non-slip processing can be surface-finished, and a tufted carpet excellent in appearance can be manufactured.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a tufted carpet according to a first embodiment of the present invention.
As shown in FIG. 1, in the surface treatment apparatus, the hair removal process unit 2, the polisher process unit 3, and the shearing process unit 4 are sequentially arranged at predetermined intervals in the feeding direction (front-back direction) of the tufted carpet 1. In the hair treatment step 2, which is the first surface treatment step, the rotating brush roll 2A is disposed on the upper side so that the vertical movement can be adjusted, and the rotating side serving as the support guide of the tufted carpet 1 is disposed on the lower side. Support roll 2B
Is arranged.

The rotation support roll 2B is rotatably supported at the upper end of a fixed member 2C, and the shape and structure of the fixed member 2C are not limited as long as the member can support the rotation support roll 2B. However, it is preferable to employ a fixed guide member in the conventional hair-pudding process section. Two sets of bristle separating means composed of the rotating brush roll 2A and the rotary support roll 2B are arranged at predetermined intervals in front and rear to constitute a bristle separating section 2.

The polisher process unit 3 and the shearing process unit 4 are known process units. The polisher process unit 3 is composed of a rotary heating roll 3A and pressing rolls 3B and 3C which are vertically movable on the front and rear sides thereof. , Two sets of polisher means consisting of these rotating heat roll 3A and front and rear pressing rolls 3B, 3C,
They are arranged at a certain interval before and after. On the other hand, the shearing process unit 4 includes a rotating roll body 4A having a spiral shearing blade 4a on the outer peripheral surface over its entire length, and a rotating roll body 4A disposed along the lower circumferential surface of the rotating roll body 4A and having a front end edge. Fixed blade 4B facing the shearing blade 4a of the rotating roll body 4A
This constitutes the shearing means.

Although not shown, a conveying means such as a driving roll for supplying and conveying the tufted carpet 1 is provided in each of the steps 2 to 4. In addition, each step 2
In the front side of 4, the interlocking dancers 5A to 5C of the respective steps in which the tufted carpet 1 is bridged are arranged, and between each of the steps 2 to 4, a plurality of tufted carpets 1 are bridged. A guide roll 6 is provided.

FIG. 2 shows a tufted carpet 1 whose surface is treated by the surface treating apparatus having the above-described structure.
As shown in the figure, a sound absorbing elastic material made of a sponge having a constant thickness is adhered to the back of a carpet main body 1 'formed by tufting an infinite number of piles 1b made of tuft yarn by a tufting machine on a base cloth 1a. 7 provided integrally, and a backing material 8 such as a nonwoven fabric adhered to the back surface of the sound absorbing elastic layer 7, or the carpet main body 1 ′ as shown in FIG. Is a tufted carpet obtained by sticking a non-slip backing material 9 made of a rubber layer on the back surface of the carpet. The backing material 8 attached to the back surface of the sound absorbing elastic layer 7 may be a non-slip backing material such as a rubber layer.

In order to finish the surface of the tufted carpet 1 by each of the steps 2 to 4 of the surface treatment apparatus, first, the tufted carpet 1 is supplied to a hair treatment step 2, which is a first surface treatment step. The backing material side is placed on the rotating support roll 2B disposed on the hair
When the rotation support roll 2B is moved backward in a state of being stretched in the shape of a letter, the rotation support roll 2B supporting the lining material of the tufted carpet 1 is moved according to the moving speed of the tufted carpet 1. The tufted carpet 1 rotates through the bristle wrapping process section 2 with little resistance from the rotation support roll 2B side, and a pile 1b formed by twisting a large number of fine yarns at the time passes through the bristle roll 2A. It is split and handled.

As described above, the rotation support roll 2B that guides backward while supporting the backing material of the tufted carpet 1 rotates in the feeding direction in synchronization with the moving speed (transport speed) of the tufted carpet 1. Therefore, in the tufted carpet 1 in which the backing material 8 is adhered to the back surface of the base cloth 1a of the carpet main body 1 'via the sound absorbing elastic layer 7, it is wrapped around the rotation support roll 2B in an inverted V-shape. Although the wrinkle-like undulations are generated in the lining material 8 and the sound absorbing elastic layer 7 is compressed and deformed, the backing material 8 passes through the back as it is in the original state according to the rotation of the rotation support roll 2B, and has no wrinkles on the sending side. Does not accumulate, so that the peeling phenomenon between the sound absorbing elastic layer 7 and the backing material 8 does not occur.

Similarly, also in the tufted carpet 1 having the non-slip backing material 9 such as a rubber layer, the non-slip backing material 9 slips due to the rotation of the rotary support roll 2B while being pressed against the rotary support roll 2B. Therefore, the pile 1b can be smoothly passed through the bristle treatment section 2 and sent to the next polisher section 3 while the pile 1b is brushed by the brush roll 2A.

The pile 1b of the tufted carpet 1 that has reached the polisher process section 3 is heat-treated in contact with the rotating heat roll 3A to change from a crimped state to a straight hair state and to impart gloss. Continuously sent to In this shearing process unit 4, the tip (upper end) of the pile 1b is cut by the spiral shear blade 4a and the fixed blade 4B of the rotating roll body 4A so that all the piles 1b are aligned at the same height. It is. Also in the polisher process section 3 and the shearing process section 4, the tufted carpet 1 is smoothly moved at a predetermined processing speed without causing separation of the sound absorbing elastic layer 7 and the backing material 8. Surface treatment can be performed.

[0020]

As described above, according to the method for finishing the surface of a tufted carpet of the present invention, the tufted carpet having a backing is removed from the surface pile by a hair treatment step, a polisher step, and a shearing step. In the surface finishing processing method of tufted carpet, which sequentially feeds and continuously finishes the surface, the rotating support roll is used as a guide for pressing the tufted carpet against the brush roll for hair treatment in the hair treatment step, Since the piles of the tufted carpet are wrapped while rotating the rotatable support rolls by the travel of the tufted carpet, the rotatable support rolls that support the tufted carpet and send out the tufted carpet to the traveling speed of the tufted carpet. Because it rotates in synchronization,
Even if the backing material is a tufted carpet in which a non-slip rubber layer is formed, or a tufted carpet in which the backing material is adhered to the back surface of the base cloth via a sound absorbing elastic layer such as a sponge. Even if there is little frictional resistance to the rotating support roll, the surface pile can be smoothly sent out while the hair pile is treated by the brush roll.

Therefore, the tufted carpet can be reliably and smoothly continuously supplied to the next polisher process section and the shearing process section via this hair-pulling process section, and the toughened carpet is layered on the back surface. It is possible to finish the surface of a tufted carpet having a non-slip treatment such as a ted carpet or a rubber layer, so that a tufted carpet excellent in appearance can be manufactured.
